PR 5211 Instrument Manual ProfiBus Interface
Sartorius EN-55
6 ProfiBus Interface
For PR 5211/00 and PR 5211/11 only.
6.1 ProfiBus Interface Protocol
The interface works with an 8-byte write window and an 8-byte read window. The ProfiBus exchanges its
data cyclically from each slave. This means: in each cycle, 8 bytes are written and 8 bytes are read also if the
data contents are unchanged.
The ProfiBus protocol ensures the data transport between ProfiBus master and the 2*8-byte data windows.
The interface protocol is below the ProfiBus level and manages the access to a large variety of data via the
8-byte wide read and write windows.
